A liquid crystal display (“LCD”) is one of the most widely used flatpanel displays, and the LCD generally includes a pair of panels providedwith field-generating electrodes, such as pixel electrodes and a commonelectrode, and a liquid crystal (“LC”) layer interposed between the pairof panels. The LCD displays images by applying voltages, respectively,to the field-generating electrodes to generate an electric field in theLC layer that determines orientations of LC molecules therein to adjustpolarization of incident light.

The LCD may include a vertical alignment (“VA”) mode LCD, which alignsLC molecules such that long axes of the LC molecules are perpendicularto the pair of panels when an electric field is not generated, has beendeveloped.

DETAILED DESCRIPTION

The exemplary embodiments will be described more fully hereinafter withreference to the accompanying drawings. As those skilled in the artwould realize, the described embodiments may be modified in variousdifferent ways, all without departing from the spirit or scope of theinvention.

The drawings and description are to be regarded as illustrative innature and not restrictive, and like reference numerals designate likeelements throughout the specification.

In the drawings, size and thickness of each element are arbitrarilyillustrated for convenience of description, and the invention is notnecessarily limited to as illustrated in the drawings. In the drawings,the thickness of layers, films, panels, regions, etc., are exaggeratedfor clarity. In the drawings, the thicknesses of layers and regions areexaggerated for convenience of description.

It will be understood that when an element such as a layer, film,region, or substrate is referred to as being “on” another element, itcan be directly on the other element or intervening elements may also bepresent. In contrast, when an element is referred to as being “directlyon” another element, there are no intervening elements present. Further,in the specification, the word “on” or “above” means positioned on orbelow the object portion, and does not necessarily mean positioned onthe upper side of the object portion based on a gravitational direction.

In addition, unless explicitly described to the contrary, the word“comprise” and variations such as “comprises” or “comprising” will beunderstood to imply the inclusion of stated elements but not theexclusion of any other elements.

Further, in this specification, the phrase “on a plane” means viewing atarget portion from the top, and the phrase “on a cross-section” meansviewing a cross-section formed by vertically cutting a target portionfrom the side.

It will be understood that, although the terms “first,” “second,”“third” etc. may be used herein to describe various elements,components, regions, layers and/or sections, these elements, components,regions, layers and/or sections should not be limited by these terms.These terms are only used to distinguish one element, component, region,layer or section from another element, component, region, layer orsection. Thus, “a first element,” “component,” “region,” “layer” or“section” discussed below could be termed a second element, component,region, layer or section without departing from the teachings herein.

The terminology used herein is for the purpose of describing particularembodiments only and is not intended to be limiting. As used herein, thesingular forms “a,” “an,” and “the” are intended to include the pluralforms, including “at least one,” unless the content clearly indicatesotherwise. “Or” means “and/or.” As used herein, the term “and/or”includes any and all combinations of one or more of the associatedlisted items.

Furthermore, relative terms, such as “lower” or “bottom” and “upper” or“top,” may be used herein to describe one element's relationship toanother element as illustrated in the Figures. It will be understoodthat relative terms are intended to encompass different orientations ofthe device in addition to the orientation depicted in the Figures. In anexemplary embodiment, when the device in one of the figures is turnedover, elements described as being on the “lower” side of other elementswould then be oriented on “upper” sides of the other elements. Theexemplary term “lower,” can therefore, encompasses both an orientationof “lower” and “upper,” depending on the particular orientation of thefigure. Similarly, when the device in one of the figures is turned over,elements described as “below” or “beneath” other elements would then beoriented “above” the other elements. The exemplary terms “below” or“beneath” can, therefore, encompass both an orientation of above andbelow.

“About” or “approximately” as used herein is inclusive of the statedvalue and means within an acceptable range of deviation for theparticular value as determined by one of ordinary skill in the art,considering the measurement in question and the error associated withmeasurement of the particular quantity (i.e., the limitations of themeasurement system). For example, “about” can mean within one or morestandard deviations, or within ±30%, 20%, 10%, 5% of the stated value.

Unless otherwise defined, all terms (including technical and scientificterms) used herein have the same meaning as commonly understood by oneof ordinary skill in the art to which this invention belongs. It will befurther understood that terms, such as those defined in commonly useddictionaries, should be interpreted as having a meaning that isconsistent with their meaning in the context of the relevant art and theinvention, and will not be interpreted in an idealized or overly formalsense unless expressly so defined herein.

Exemplary embodiments are described herein with reference to crosssection illustrations that are schematic illustrations of idealizedembodiments. As such, variations from the shapes of the illustrations asa result, for example, of manufacturing techniques and/or tolerances,are to be expected. Thus, embodiments described herein should not beconstrued as limited to the particular shapes of regions as illustratedherein but are to include deviations in shapes that result, for example,from manufacturing. In an exemplary embodiment, a region illustrated ordescribed as flat may, typically, have rough and/or nonlinear features.Moreover, sharp angles that are illustrated may be rounded. Thus, theregions illustrated in the figures are schematic in nature and theirshapes are not intended to illustrate the precise shape of a region andare not intended to limit the scope of the claims.

Now, a display device according to an exemplary embodiment will bedescribed with reference to FIGS. 1 and 2 as well as other accompanyingdrawings.

The extending directions of the minute branch parts194 of two adjacent sub-regions may be crossed.

The pixel electrode 191 may further include an outer branch part 195connecting end parts of the minute branch parts 194. The outer branchpart 195 may mainly extend in the transverse direction. Accordingly, theouter branch part 195 may be positioned on an upper edge and a loweredge of the pixel electrode 191. However, the invention is not limitedthereto, and the outer branch part 195 may be further positioned on aleft edge and a right edge of the pixel electrode 191, while the outerbranch part 195 positioned on the left edge and the right edge of thepixel electrode 191 may extend in the longitudinal direction.
